GNSS SPOOFING DETECTION FOR CRITICAL INFRASTRUCTURE

SECURING THE
TRUST LAYEROF GLOBAL PNT INFRASTRUCTURE

Angulus is a physical-layer intelligence platform that checks satellite navigation signals at the radio level — and tells operators when position or time can no longer be trusted.

Eight classes of critical infrastructure — every one of them trusting the same faint signal from orbit, and none of them able to check it. Select a node to see what it depends on.

02 / WHO WE ARE

THE THREAT IS PHYSICAL. SO IS THE DEFENCE.

PRODUCT · ANGULUS
ESA BIC PADUA

Astralis Sys builds resilient positioning, navigation and timing systems. Our product is Angulus — GNSS spoofing detection for critical infrastructure.

We are selected for ESA BIC Padua — the European Space Agency's business incubation centre in Padua — and we are building the trust layer of global PNT infrastructure: the continuous verification that critical systems currently lack.

"To secure and build resilient systems for position, navigation and timing across 6G networks."

03 / OUR PEOPLE

BUILT BY RESEARCHERS, ASTROPHYSICISTS AND AI ENGINEERS

A MULTIDISCIPLINARY TEAM
PADOVA · ITALY

A team whose heritage runs from ESA programme research to production AI shipped in real deployment environments.

Researchers

RIGOUR

A research-grade culture: every performance claim is designed to be independently verifiable — benchmarked before it is ever stated.

Astrophysicists

HERITAGE

Deep roots in astrophysics and space science, including ESA programme research — fields where results have to survive scrutiny.

AI Engineers

PRODUCTION

Production AI experience — systems shipped across real deployment environments, not just the lab.

04 / THE PROBLEM

CRITICAL SYSTEMS TRUST GNSS WITHOUT CHECKING IT

GNSS · GPS · GALILEO
A SIGNAL BELOW THE NOISE

TELECOM NETWORKS

5G/6G cells synchronise to GNSS-disciplined clocks.

DATA CENTRES AND FINANCE

Timestamps and logs depend on GNSS time.

GROUND STATIONS AND MARITIME

Operations follow GNSS position and time.

ESPECIALLY EXPOSED

Network timing: one spoofed GNSS feed can corrupt timing across many cells at once.

Receivers cannot tell a fake signal from a real one.

The answer to both trust questions is the same: GNSS — GPS, Galileo. A signal weaker than background noise. Message-level authentication like Galileo OSNMA exists — but it is bypassed entirely by record-and-replay spoofing, a physical-layer attack that no cryptographic signature can stop.

A THREAT THAT IS DOCUMENTED, NOT THEORETICAL

Continental-scale outages, vessels simultaneously displaced onto false coordinates, cockpit signal loss logged daily — spoofing and jamming incidents are now recorded at a scale no critical operator can ignore.

The threat is not theoretical. It is happening now, at scale.
T = 0 T = 1.2 S T = 4–6 S Attack begins Angulus detects Incumbent alert fires
DANGER ZONE — COMPROMISED PNT ENTERING OPERATIONAL SYSTEMS UNDETECTED

FINANCE

A platform timestamps thousands of trades against a spoofed clock.

MiFID II breach — silently broken

MARITIME

A vessel drifts off course before any bridge alarm fires.

Liability exposure — no evidence trail

PORTS

Automated cranes & AGVs mis-position cargo against a false fix.

Terminal halt — cascading throughput loss

AVIATION

A GNSS approach is guided onto coordinates that no longer exist.

EASA SIB 2022-02R3 — safety-critical

DATA CENTRE

Corrupted timing propagates through transaction logs.

DORA Art. 17 — irreversible

TELECOM

One event desyncs every 5G base station in range — ns drifts to µs.

Handovers corrupt network-wide

AUTONOMOUS · AV & DRONES

A vehicle or UAV trusts a spoofed position with no human in the loop.

Physical safety — no fallback authority

REGULATORY EXPOSURE

DORA fines reach 2% of global annual turnover. DORA, NIS2 & EASA SIB 2022-02R3 mandate continuous, verifiable timing integrity.

05 / INTRODUCING ANGULUS

A PHYSICAL-LAYER INTELLIGENCE PLATFORM

PRODUCT · ANGULUS
ACTIVE DEVELOPMENT

The hardware to survive an attack — atomic clocks, antenna arrays — already exists on the market. What the ecosystem lacks is the intelligence to orchestrate it. Angulus is that intelligence — the trust layer that verifies position, navigation and timing, and defends it, before any receiver is compromised.

WHAT ANGULUS DELIVERS

GNSS threats are caught before any receiver on site is compromised — measured, end to end, hardware-in-loop.
BEFORE THE RECEIVERMEASUREDHARDWARE-IN-LOOP
A continuous Timing Trust Bound — a living confidence score, not a binary alarm. Integrity becomes something you watch, not something you find out about.
CONTINUOUSCONFIDENCE-QUALIFIEDNOT A BINARY ALARM
Evidence for DORA, NIS2 and EASA SIB 2022-02R3 — cryptographically signed and built in, so compliance is a by-product of operation, not a project.

Operations continue on trusted time and position through an attack — zero operator intervention.
PNT MAINTAINEDZERO OPERATOR INTERVENTION
Angulus is not a faster alarm. It is a different layer of physics — and the only one that closes the regulatory gap end to end.

06 / RESULTS

PROPER RESULTS. MEASURED.

RECORDED BENCHMARK DATA
VALIDATED END-TO-END

Angulus is a working system, not a concept. The detection pipeline runs end to end, and every performance claim is designed to be independently verifiable on recorded benchmark spoofing data.
